Pneumatically actuated hydraulic multi metering device.

摘要

Pneumatically actuated hydraulic multimetering device of the type of those formed by a cylinder, the actuation of which in turn gives rise to the actuation of a series of working cylinders, and is characterised by the fact that the piston (2) of the pneumatic cylinder (1) is equipped with rods (3) which are non-detachable therefrom and remain in relation with the respective sleeves connected to a cover of the pneumatic cylinder (1) in order to form the metering cylinders, so that each of the sleeves (4) remains connected via a pipe (7) to the sleeve (5) of the corresponding working cylinder (8), knowing that the displacement en masse of the pistons (9) of the working cylinders (8) is given a uniform movement independently of the loads which are they withstanding. <IMAGE>
